Renku Python Library, CLI and Service¶
A Python library for the Renku collaborative data science platform. It includes a CLI and SDK for end-users as well as a service backend. It provides functionality for the creation and management of projects and datasets, and simple utilities to capture data provenance while performing analysis tasks.
renku-pythonis the python library and core service for Renku - it does not start the Renku platform itself - for that, refer to the Renku docs on running the platform.
We do not officially support Windows at this moment. The way Windows handles paths and symlinks interferes with some renku functionality. We recommend using the Windows Subsystem for Linux (WSL) to use renku on Windows.
First, install pipx
and make sure that the
$PATH is correctly configured.
$ python3 -m pip install --user pipx $ python3 -m pipx ensurepath
pipx is installed use following command to install
$ pipx install renku $ which renku ~/.local/bin/renku
pipx installs renku into its own virtual environment, making sure that it
does not pollute any other packages or versions that you may have already
If you install renku as a dependency in a virtual environment and the
environment is active, your shell will default to the version installed
in the virtual environment, not the version installed by
To install a development release:
$ pipx install --pip-args pre renku
$ pip install renku
The latest development versions are available on PyPI or from the Git repository:
$ pip install --pre renku # - OR - $ pip install -e git+https://github.com/SwissDataScienceCenter/renku-python.git#egg=renku
Use following installation steps based on your operating system and preferences if you would like to work with the command line interface and you do not need the Python library to be importable.
The containerized version of the CLI can be launched using Docker command.
$ docker run -it -v "$PWD":"$PWD" -w="$PWD" renku/renku-python renku
It makes sure your current directory is mounted to the same place in the container.
Interaction with the platform can take place via the command-line interface (CLI).
Start by creating for folder where you want to keep your Renku project:
$ renku init my-renku-project $ cd my-renku-project
Create a dataset and add data to it:
$ renku dataset create my-dataset $ renku dataset add my-dataset https://raw.githubusercontent.com/SwissDataScienceCenter/renku-python/master/README.rst
Run an analysis:
$ renku run wc < data/my-dataset/README.rst > wc_readme
Trace the data provenance:
$ renku log wc_readme
These are the basics, but there is much more that Renku allows you to do with your data analysis workflows.
